Designing a clean room to meet ISO standards requires careful coordination. The designer must balance contamination control with regulatory compliance and operational functionality. At Jade Aden Interiors, we integrate technical performance with practical layout planning. This allows us to create clean rooms that support your team’s workflow.

1. Airflow & Contamination Control

Effective particle control is the foundation of clean room performance and begins with:

• HEPA or ULPA filtration: Removing 99.97% of particles ≥0.3µm
• Controlled Air Changes Per Hour (ACH): Typically 30–60 for ISO 7 and 10–25 for ISO 8
• Positive Pressure Systems: Preventing airborne ingress from adjacent areas

When necessary, we create directional airflow systems, utilising either laminar or turbulent flow. Our experts ensure these systems comply with ISO 14644-3 validation protocols. For projects in regulated environments, this ensures airborne contamination stays within permitted limits. Most importantly, it continues to do so even at peak operation.

2. Material Specification

Surfaces, including walls, ceilings, and flooring, must be:

• Non-porous, resistant to microbial growth, and easy to sanitise
• Resistant to cleaning agents and chemical exposure
• Smooth and free from joints or edges to minimise particle accumulation

We install hygienic wall systems, ceiling cladding and seamless flooring designed for clean room use. As a Komfort registered installer, our solutions are tested and compliant with industry standards. They provide lasting durability while maintaining high standards of hygiene.

3. Clean Room Layout & Zoning

A compliant clean room layout must manage traffic flow and minimise the risk of cross-contamination. This includes:

• Airlocks or gowning areas to separate external and internal zones
• Defined personnel and material routes to prevent crossover
• Segregated areas between clean and less clean operations (e.g. ISO 8 to ISO 7)

Our design team collaborates with clients to understand their process flows, regulatory requirements, and spatial constraints. In temperature-controlled labs and pharmaceutical settings, we also design transitions for regulated zones. These features include pass-through hatches and decontamination points.

4. Compliance, Validation & Sector-Specific Standards

To achieve a clean room design, it’s vital to closely follow international and industry standards. Our team ensures alignment from day one by incorporating the following:

• ISO 14644 classifies air cleanliness levels from ISO 1 to ISO 9. These levels depend on the allowed particle concentrations.
• EU GMP Annex 1 applies to pharmaceutical and sterile manufacturing. It includes layout design, environmental monitoring, and cleaning validation. The UK’s MHRA regulates these areas.
• BRCGS alignment is crucial for food production and the use of medical devices. It helps meet both integrated and dual-standard compliance requirements.

We also support your validation process, from airflow qualification to recovery time testing. This helps ensure your facility meets its ISO classification, both when idle and during operation. Our approach is built to help you pass audits, protect processes, and maintain trust.

5. Lighting, Visibility & Operational Safety

Lighting is commonly overlooked in clean room design. However, it significantly affects visibility, safety, and the accuracy of inspections. We specify LED systems that are:

• Flush-mounted with sealed enclosures to minimise particle accumulation
• Low-glare, high-lux lighting that supports visual inspections and safe operation
• Energy-efficient systems, with compatibility for centralised lighting controls

Emergency and task-specific lighting can be added when necessary. All fixtures should be rated for the appropriate Ingress Protection (IP) levels for clean rooms.
